I'm sorry if you believe I'm not searching on my own (because I searched, but I have some difficulties to define good keys word in English to got good research results).

Did I made a mistake in my web.xml (see my first message of this thread for my web.xml extract)? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4000966#...
